In Figures 7 vand s, there 'is shown a1 slightly modified means for connecting the plunger-actuating means with the shackle 8. VThis means con-V sists of a clamp bracket '70 composed of two sections '7l and 72, each of which is provided with' a recess adapted to receive therein a respective side edge of one of the side members 32 of the shackle 8, and Athese members'are ysecured in "clamping relation upon the member 32 by means of a clamping bolt '73 `which extends through registering' apertures provided in the sections 71: and '72.'V .Y

One of the sections 7.1 of the bracket '70 is pro# Y vided with alaterally extending stud v75 which y VV extends outwardly fromone face thereof ina" plane intermediate the'upper andlowei" shackle bolts37 and 38 andha's rotatably mountedthereon one end of lthe plunger-actuating link 25A which 'i may, as shown, be adjustably mountedupon the Vstud 75 in alignment with'the plunger 16 by means of nuts 76screw-,threaded onthefouter Vend of the Vstud 75 and positioned'V oneV adjacentAv either face of the link 25.
